Thermodynamics of Various Entropies in Specific Modified Gravity with Particle Creation

open access: yesAdvances in High Energy Physics, 2018
We consider the particle creation scenario in the dynamical Chern-Simons modified gravity in the presence of perfect fluid equation of state p=(γ-1)ρ. By assuming various modified entropies (Bekenstein entropy logarithmic entropy, power law correction ...

Non-equilibrium Thermodynamics and Fluctuations [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2003
In the last ten years, a number of ``Conventional Fluctuation Theorems'' have been derived for systems with deterministic or stochastic dynamics, in a transient or in a non-equilibrium stationary state.

Toward the Relational Formulation of Biological Thermodynamics

open access: yesEntropy, 2023
Classical thermodynamics employs the state of thermodynamic equilibrium, characterized by maximal disorder of the constituent particles, as the reference frame from which the Second Law is formulated and the definition of entropy is derived.

The mereology of thermodynamic equilibrium [PDF]

open access: yesSynthese, 2021
AbstractThe special composition question (SCQ), which asks under which conditions objects compose a further object, establishes a central debate in modern metaphysics. Recent successes of inductive metaphysics, which studies the implications of the natural sciences for metaphysical problems, suggest that insights into the SCQ can be gained by ...

Nonequilibrium thermodynamics in cavity optomechanics

open access: yesFundamental Research, 2023
Classical thermodynamics has been a great achievement in dealing with systems that are in equilibrium or near equilibrium. As an emerging field, nonequilibrium thermodynamics provides a general framework for understanding the nonequilibrium processes ...

Linear stochastic thermodynamics

open access: yesNew Journal of Physics, 2022
We study the thermodynamics of open systems weakly driven out-of-equilibrium by nonconservative and time-dependent forces using the linear regime of stochastic thermodynamics. We make use of conservation laws to identify the potential and nonconservative

Thermodynamics of scale-dependent Friedmann equations

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
In this work, the role of a time-varying Newton constant under the scale-dependent approach is investigated in the thermodynamics of the Friedman equations.

Thermodynamics “beyond” local equilibrium [PDF]

open access: yesProceedings of the National Academy of Sciences, 2001
Nonequilibrium thermodynamics has shown its applicability in a wide variety of different situations pertaining to fields such as physics, chemistry, biology, and engineering. As successful as it is, however, its current formulation considers only systems close to equilibrium, those satisfying the so-called local equilibrium hypothesis.

Multiscale Thermodynamics

open access: yesEntropy, 2021
Multiscale thermodynamics is a theory of the relations among the levels of investigation of complex systems. It includes the classical equilibrium thermodynamics as a special case, but it is applicable to both static and time evolving processes in ...

Entropy and the Second Law of Thermodynamics—The Nonequilibrium Perspective

open access: yesEntropy, 2020
An alternative to the Carnot-Clausius approach for introducing entropy and the second law of thermodynamics is outlined that establishes entropy as a nonequilibrium property from the onset.
